Power over Ethernet (PoE) controllers are an important component of modern communication and other industrial networks, providing power to connected devices without any need for additional wiring. The SI3452D-B02-GMR is a part of the Silicon Laboratories’ Family of Si3452 PoE Controllers and offers a complete power source equipment (PSE) solution that has been designed to meet the IEEE 802.3af and 802.3at power sourcing requirements. In addition to the power sourcing capabilities, the controller also provides extensive LED lighting control, which is essential for PSE applications.

The SI3452D-B02-GMR provides an advanced power management solution that enables designers to quickly integrate PoE capability into their products with minimal effort. The power sourcing and LED control are controlled via an integrated microcontroller that implements an embedded software-based on the IEEE 802.3af and 802.3at standards. The controller is capable of sourcing up to 15.4 watts of power to a powered device (PD) over a four-pair cable, with each pair capable of delivering up to 1.4 watts. It is also capable of sourcing up to 33 watts of power to a PD over a two-pair cable.

The SI3452D-B02-GMR is also capable of providing a comprehensive lighting control solution, enabling LEDs to be dimmed or intensified from the PSE systems. This eliminates the need for manual adjustment of the LED lights. The controller features an integrated Color Correction Engine that enables analog control of the LED intensity or color. The control is provided in an intuitive graphical user interface (GUI) based on the Color Control SDK developed by Silicon Laboratories.

The SI3452D-B02-GMR is designed with a comprehensive feature set that is optimized to provide reliable, robust power even in challenging environments. It is built with a robust voltage and current monitoring system that can detect and protect against variances in mains operating power, allowing for power source fault correction and protection against overvoltage events. The device is also capable of fault containment in the event of a power block or a load disconnect or misapplication.

In addition, the SI3452D-B02-GMR has a wide range of system monitoring capabilities, including real-time diagnostics of voltage and current, LED lighting control and port status, as well as support for PD classification and power management. The device also supports a variety of operating modes, including single-port, dual-port and multi-port operation. This feature set is designed to make the SI3452D-B02-GMR an ideal solution for both consumer and enterprise applications.

Overall, the SI3452D-B02-GMR offers an advanced PoE controller combined with a comprehensive lighting control solution that is designed to make integration and evaluation of PoE systems quick and easy. With its robust power sourcing capabilities, sophisticated power monitoring system and rich feature set, the SI3452D-B02-GMR is an ideal choice for a wide range of PoE applications.
